Alright, so umm seriously the answer should be C also in the question Diagram Y. So, here it is cod liver oil which is semi-liquid = Half liquid and half solid. U can push it a little bit so the answer is C. In the book, it is turmeric powder and the answer is showing B too! I mean powder like seriously. The answer in the book should be D also in the book called Diagram Z. It is POWDER!!!!!!!!!!!!!!!!!!!! Like seriously Powder! They need to understand before writing the question in the book.

Dear friends, the answer is D. There has been an error by the SOF team. Cod liver oil is a liquid, so it will flow out. As diagram Z is showing precisely that, the answer is D.

Ans 12:

Karthik from Euro, Bengaluru
Class : Class 7
no it is 12 as one piece has two poles so north poles and south poles =6 6=12

Ans 13:

Ashwak from Cambridge, Jalandhar
Class : Class 9
IT is not correct .... because they did not ask total number of poles ....it should be A {SIX}

Ans 14:

Ashwak from Cambridge, Jalandhar
Class : Class 9
It is incorrect as there are six north poles and six south poles present in a magnet if it is broken into six pieces

Subject :NSO    Class : Class 6

Ans 1:

Mohit Shekher from ST Andrews School, Secunderabad
Class : Class 7
Sorry R would be the south pole because of the reason:Q becomes the North pole, and R, where the magnet is lifted becomes the south pole.

Ans 2:

PAYAL from DPS BHILAI, BHILAI
Class : Class 8
it has started magnetising from Q SO THATS WHY IT IS TELLING THAT Q WILL BE THE NORTH SEEKING POLE.

Ans 3:

Ayansh Mallick from Birla Open Minds, Hyderabad
Class : Class 7
The answer is P as you can clearly see the iron rod should allow the magnetism to flow like what happens when you chain a nail, even though you are affecting only the top part the whole screw is affected hence proving the answer is wrong

Ans 4:

Shuvangi Das from Vivekananda mission school, haldia
Class : Class 9
Will P be the North Pole or Q? So confusing!!🤔🤔

Ans 5:

Ayansh Mallick from Birla Open Minds, Hyderabad
Class : Class 7
A

Ans 6:

Tamrashi Pani from National Public School, Bangalore
Class : Class 8
The answer is B

Ans 7:

Dushyant Singh from Shree Ram Centenial School, Indore
Class : Class 9
see the solution the magnet gets in contact with q so it is the correct ans

Ans 8:

Vivaan Kumar from Heritage Xperiential Learning School, Gurgaon
Class : Class 8
B IS A WRONG ANSWER.

Ans 9:

Shourya Ganesh from The Green Acres Academy, Mumbai
Class : Class 9
It should be a

Ans 10:

Mohit Shekher from ST Andrews School, Secunderabad
Class : Class 7
In the above process of magnetisation, the magnet makes its first contact with the iron rod on place R, so R would be the North pole of the magnetised iron bar.

Ans 11:

Ashwak from Cambridge, Jalandhar
Class : Class 9
Yes it should be A ......because it is not possible that some of the iron bar is magnet and some is iron ....in the given figure starting of the stroke is point is Q but before that is point P which is starting of the rod so the CORRECT answer is A ..

Ans 12:

Devavrat Sharma from Podar International School Powai, Mumbai
Class : Class 7
The correct answer is (B) because Q is the first point of contact.

Ans 13:

malhar thorve from city internqtional school, satara road, pune
Class : Class 7

Ans 14:

Aadhira from velammal new gen school, Medavakkam, Chennai
Class : Class 6
The correct answer is (B),Q because the magnetic contact starts on Q and not on P.

Ans 15:

Tamrashi Pani from National Public School, Bangalore
Class : Class 8
I agree with jigishal

Ans 16:

Manya Pujar from EuroSchool, Davangere
Class : Class 6
A IS TH CORRECT ANSWER. In the figure they started stoking the iron piece from point P which is the starting of the iron rod. so the correct answer is A.....

Ans 17:

Ayansh Mallick from Birla Open Minds, Hyderabad
Class : Class 7
A

Ans 18:

Ashmi Narkar from The Shishukunj International School, Jhalaria Campus, Indore
Class : Class 9
Q or R?????? PLEASE EXPLAIN MASTER ANSWER!

Ans 19:

Navya from Gyanshree, Noida
Class : Class 6
IT WILL BE P!

Ans 20:

Shayan Bari from Kendriya Vidyalaya, Katihar
Class : Class 7
The poles are end point of the magnet ,so the north pole should be P.

Ans 21:

Tejas Singh from Freedom International School, Bangalore
Class : Class 6
I didnt understand how it is R, can someone explain? Because according to me, the first point of contact is Q, but maybe that's not how it works....

Ans 22:

Sharanyaa Tripathi from Uttam school for girls, Ghaziabad
Class : Class 8
If you clearly notice, the arrow is first coming in contact with Part Q, and the arrow is above in Part P. First, the magnet comes in contact with part Q, so when the iron rod is magnetised, Part Q will be North pole.

Ans 23:

Naman from Svm, Nalasopara
Class : Class 6
N POLE ALWAYS GIVE THAT'S WHY A

Ans 24:

ADVAY BANSAL from LOTUS VALLEY INTERNATIONAL SCHOOL GURUGRAM, GURUGRAM
Class : Class 6
As north seeking pole is geographic south pole so R is north seeking pole. so , basically the south pole is the north seeking pole and as the north pole is facing downwards and starting with Q so south pole will be R . Hence, R is the north seeking pole and option C is the correct option.

Ans 25:

Veda Dua from Delhi Public School, R. K. Puram, New Delhi
Class : Class 10
The magnet first makes contact with Q, so, it is the North Pole of the magnet

Ans 26:

Shreeya Mangla from ASN Senior Secondary School, New Delhi
Class : Class 9
At first, I also thought that it will be A but if you see the figure closely, you can see that the magnet first comes in contact with point Q, it is rubbed till R and is then lifted at R point. So, Point Q would be the north pole and the point R would be the south pole

Ans 27:

Jigishal Thool from Don Bosco School, Guwahati
Class : Class 6
AS NORTH POLE INTRODUCED AT Q PART OF THE IRON ROD SO Q WILL BE NORTH POLE.

Ans 28:

Shaurya from Mris 51 Gurugram, Gurugram
Class : Class 7
it will be P!!!!!!!!!!!!!
